Abstract

This research work is dedicated to the development of efficient thermal insulation materials using diatomite and industrial waste. The application of the hydration hardening method allows for the creation of structurally stable composite materials with high thermal insulation capacity.
In the course of the research, the ratios of the components were optimized, as well as the parameters of hydration hardening to achieve optimal modes for obtaining thermal insulation materials. The developed materials have the potential for use in construction and other industries, contributing to improved energy efficiency and a reduction in the use of traditional materials, which contributes to sustainable development and a decrease in environmental impact. In this study, compositions of thermal insulation materials based on natural diatomite and technogenic waste (ash, slag) were developed using cement and gypsum as binders. The obtained materials demonstrate good physical and mechanical properties: low thermal conductivity coefficient of 0.336 W/m*K and high strength of 10.2 MPa after 30 days of hardening. The materials have acceptable water absorption coefficients, which ensures their durability and resistance to moisture.
Thus, the present study opens up new possibilities for the creation of environmentally friendly, cost-effective thermal insulation materials based on diatomite and technogenic waste. The developed materials can find wide application in various fields of industry, which emphasizes the importance and relevance of the work carried out.
